OK, I have UVWTags figured out. Please correct the documentation for UVWTag.SetSlow so that the types of a..d are Vector, not int.... believing they were int I tried for a while to pass in UV vertex indices and pass in the actual data with SetAllHighlevelData but that was a big fail. I have to say I'm a bit concerned when I have to call something named GetSlow thousands of times in a row.

I'm assuming there must be a similar way to set up a NormalTag but I don't see anything to support that idea.... I can jam a lot of normal data into a VariableTag, but what is the right type? And should it be 4 normals per facet as with UVWs?
